What is Poka-Yoke in Manufacturing?

Poka-yoke, or mistake-proofing, is a Japanese lean manufacturing strategy for eliminating human mistakes during production in order to prevent product defects. In Japanese, poka-yoke translates roughly to “avoid” (yokeru) and “mistakes” (poka). Lean manufacturing is the act of reducing waste while maximizing productivity to boost shop floor operations.

Essentially, this technique works to remove product deficiencies by preventing or immediately fixing human mistakes as they occur. Leaders use lean manufacturing tactics like mistake-proofing to cut waste, reduce costs, optimize procedures, increase innovation, and decrease time to market.
